Question

我有像这样的Json对象

{
   "  resultArr": [
                   {
                     "ID":"1",
                      "0":"1",
                      "APPROVAL LEVEL":"1",
                      "1":"1",
                      "WorkFlow Type Code":"1",
                      "2":"1",
                      "Employee Number":"825489602V",
                      "3":"825489602V",
                      "Employee Name":"Wajira Wanigasekara",
                      "4":"Wajira Wanigasekara"
                     }
                 ]
}

我正在尝试打印resultArr的键和值。

例如，我想打印ID = 1 APPROVAL LEVEL = 1 ..就像那样

我可以使用此代码

获取ID，APPROVAL LEVEL ..的值

$.ajax({
                    type: "POST",
                    async:false,
                    url: "<?php echo url_for('workflow/getApprovalByModuleView') ?>",
                    data: { viewName: viewName },
                    dataType: "json",
                    success: function(data){

                        alert(data.resultArr[0][3]);
                    }
                });

但我想打印那些名字......

这意味着我想要打印data.resultArr数组的KEY和VALUE

我该怎么做？

Answer 1

你使用键来选择值。我能想到的唯一方法是通过它们循环：

$.each(data.resultArr, function(index, value) { 
  alert(index + ': ' + value); 
});

Answer 2

我很确定您获得的data变量是成功的参数，并不是您所期望的。

首先，弄清楚数据实际包含的内容。我建议安装Firebug而不是警告写：

console.dir(data);

同样要检查数据类型，请尝试：

console.log(typeof(data));

现在您知道您的数据实际返回的格式，您可以继续处理它。

Answer 3

的javascript：

var array = {"key" : "value", "anotherkey" : "anothervalue"};
for (key in array){
    document.write("For the Element " + "<b>"+array[key]+"</b>" 
  + " Key value is  " +"<b>"+key+"</b>"+"<br>");
}

这将从javascript中获取数组中的键和值。

你遇到的问题是我认为你正在访问两个不同的数组对象。

data.resultArr[0][3]与data.resultArr[0]["3"]不同，后者与data.resultArr [0]不相同[“员工编号”] . The first will give you the VALUE for审批级别the second will give the the SECOND employee number and the last will give you the value for员工编号`。

Answer 4

您可以使用以下代码：

var json = {"resultArr":[{"ID":"1","0":"1","APPROVAL LEVEL":"1","1":"1","WorkFlow Type Code":"1","2":"1","Employee Number":"825489602V","3":"825489602V","Employee Name":"Wajira Wanigasekara","4":"Wajira Wanigasekara"}]};

var data = json.resultArr[0];
for (var key in data){
    document.write(key+":" + data[key]);
}

Answer 5

也许这会有所帮助：


function getArrayKeyAndValue(array, index){
    var count = 0;
    for (key in array){
        if(++count == index)
            return [key, array[key]];
    }      
}

var array = {"key1" : "value1", "key2" : "value2", "key3" : "value3"};
document.write(getArrayKeyAndValue(array, 1));

输出为：“key1，value1”;

Answer 6

var json = {"resultArr":[{"ID":"1","0":"1","APPROVAL LEVEL":"1","1":"1","WorkFlow Type Code":"1","2":"1","Employee Number":"825489602V","3":"825489602V","Employee Name":"Wajira Wanigasekara","4":"Wajira Wanigasekara"}]};

for(var key in json.resultArr[0]) {
    console.log( key, json.resultArr[0][key] );
}
